Authorities have arrested a Florida man who was out on bond for assaulting another man in the head with a brick after they say he killed another man with a hammer.

Polk County Sheriff's officials say 27-year-old Calvin Michael Ross and 38-year-old Johnathon Michael Miller were arguing outside a residence Saturday night. Witnesses told authorities they heard a thud and that Ross quickly went inside and into his room. He allegedly told a roommate that Miller was on the ground and needed to be checked on.

Ross is being charged with second-degree murder with a weapon and violation of pretrial conditions. He was out of probation for an aggravated assault that took place in April.
